Trix Editor custom form input component for SimpleForm

trix_editor_input.rb

# I was using https://github.com/maclover7/trix to do:
#
# f.input :my_input, as: :trix_editor
#
# Its currently been over two weeks since Rails 5.2 was released, and the 
# gem was the only thing preventing me from using it in multiple projects:
# https://github.com/maclover7/trix/pull/61#issuecomment-384312659
#
# So I made this custom simpleform input for my apps to prevent this from happening again in the future.
